The main methods in performing the study of the adsorption properties of hyperdispersant on atrazine surface were fourier transform infrared spectroscopy (FTIR) and FT-Raman spectrometer (FT-Raman), and the results suggested that the hydrogen bond force was the main force combining the surface of atrazine particles and the dispersant. And it also promoted the adsorption of dispersant on atrazine particles. However, the information of what accurate quantity of the dispersant adsorbed on the surface of atrazine should a successful suspension ability of the suspension concentrate acquire is still not available. And researches on this question still need to be done with the help of quantized spectroscopy method. The result of this study provided a theoretical foundation for the development of stable atrazine suspension concentrate and the spectroscopy quantitative analysis of it. This result provided significant information for the application of atrazine suspension concentrate at the same time.
